Figure 1: Schematic representation of UVC-based direct tracheo-bronchial UVR applications: (a) Appropriate UVC source with a fiberoptic adapter; (b) direct bronchoscopic application of UVC; (c) placement of indwelling diffusive optical fiber conduits, terminating in mainstem bronchi bilaterally. Note that radiation intensity should be limited to not more than 2.5 mW and that treatments should be applied every 4 h, with at least 24 h of therapy before reassessment. Discontinuation of treatment should be determined by the treating physician, after considering: (a) the status of patient condition and (b) the safety and efficacy of the treatment. Note: UVB (280-289 nm to 315-320 nm) or UVA (314-320 nm to 400 nm) can be used interchangeably with UVC within the proposed framework. UVR = Ultraviolet radiation, UVA = Ultraviolet A, UVB = Ultraviolet B, UVC = Ultraviolet C
